Description

A method for cultivating white birch bag seedlings in light substrate by using corn cobs

technical field

The invention relates to a method for cultivating bag seedlings of birch light substrate.

Background technique

White birch (Betula platyphylla Suks.) is a deciduous tree belonging to the Betaceae Betula genus. It is one of the main broad-leaved associated tree species in Northeast China and is widely distributed. Birch is a good economic timber tree species with high ornamental value.

Light-substrate bag seedlings are a new type of seedling cultivation technology that uses agricultural and forestry wastes as cultivation materials, uses mesh bags made of easily degradable non-woven materials as containers, and uses transplanting for planting.

At present, the growth of white birch seedlings is slow, and it cannot achieve annual uphill afforestation. The survival rate of transplanting is not high, and the weight of the substrate is heavy, which is not convenient for transportation.

Contents of the invention

The present invention aims to solve the problems that the existing white birch seedling cultivation method grows slowly, cannot achieve annual uphill afforestation, the survival rate of transplanting is not high, and the weight of the substrate is heavy and inconvenient to transport. seedling method.

The present invention utilizes the cob of corn to cultivate the method for the bag seedling of white birch light substrate, carries out according to the following steps:

1. Corn cob treatment method: crush the corn cob directly into a size of 0.2-0.5 mm with a pulverizer, add a decomposing agent, and then add water until the water content is 60%. Store at room temperature;

2. Preparation of light substrate: Take 40-50 parts by volume of corncobs treated in step 1, 25-40 parts of larch humus and 20-25 parts of vermiculite and mix evenly, add 10 parts of water to make the substrate moist , and then packed into a non-woven mesh bag of diameter × height = 13cm × 14cm to obtain a substrate bag;

3. Transplanting: Soak the matrix bag in water for 24 hours, and when the birch seedlings grow 2 to 3 true leaves, transplant the birch seedlings into the matrix bag and grow them in a plastic greenhouse.

The water content in step 1 refers to the mass percentage concentration.

In step 2, the larch humus is the under-tree humus of larch.

Compared with prior art, the beneficial effect that the present invention has is:

1) The light matrix material used in the present invention has easy source, low cost and easy processing.

2) The light substrate adopted in the present invention has good water absorption and permeability, high organic matter content, is beneficial to the growth of plant roots, and improves the survival rate of white birch seedlings.

3) The seedlings cultivated by the light substrate bag seedling method adopted by the present invention are light in weight, easy to transport, and can be directly transported to carry out afforestation up the mountain, reducing the process of retransplantation. Compared with the bare root seedlings in the field, not only the survival rate of afforestation becomes higher , and the production cost and afforestation cost are also reduced accordingly.

4) The light substrate materials used in the present invention are all agricultural and forestry wastes, and the traditional seedling raising substrate peat soil and peat soil are not used any more, which can effectively alleviate the problem of the shortage of non-renewable resources peat soil and peat soil. Moreover, the energy can be effectively recycled, and the environmental pollution during the disposal of agricultural and forestry wastes can be reduced.
